Definitions

  • the present invention relates to a method for controlling insect pests with vibrations.
  • Vibrations are known to be an important and common signal for insects that cause behaviors such as repellence, attraction, mating, feeding, oviposition and the like. Therefore, it may be possible to control the behavior of various insect pests by artificially controlling a vibration signal. Examples of such control include positive behavior control against beneficial insects and negative behavior control against insect pests. Examples of positive behavior control include the attraction to a target insect pest of natural enemies and predators used as an insect pest control resource, the attraction of pet insect beetles, and the settlement of honey bees, which are domesticated insects. Further, examples of negative behavior control include controlling an insect pest through repellence or by inhibiting its mating, feeding, oviposition and the like.
  • an insect pest control method that uses vibrations that propagate through wood is an example of insect pest control that utilizes such behavior control. Since this method can be thought of as a physical control, it has the advantage of not suffering from the problem of chemical resistance, which is a universal problem for chemically synthesized pesticides, or the problem of having an adverse impact on the human body, the environment, or a non-target organism. Therefore, this method will contribute to the development of environmentally-friendly insect pest control technologies as a substitute for chemical agents that for a long time have been demanded by society due to the appearance of insect pests that have resistance to chemical agents and increased awareness about environmental and food safety.

  • the present invention relates to the above-described method for controlling an insect pest, wherein the insect pest is one or two or more species selected from among termites or cockroaches.

  • Non-Patent Document 3 As described above, it is known that insect behavior is controlled when an insect detects vibrations, especially vibrations of a specific frequency and amplitude (Non-Patent Document 3). Further, as described above, examples of attempts to control an insect pest using vibrations are also known (Non-Patent Documents 1 and 2). However, it was not known until now that for such control it is essential to specify the vibration frequency and amplitude that are required to control insect pest behavior, and to precisely control that frequency and amplitude. Moreover, no adequate control effect has ever been proven based on such a control attempt. Therefore, enabling an insect pest to be controlled with vibrations, which is an advantageous effect of the present invention, is a remarkable effect that could not have been expected based on the conventional art.
  • the term "habitat medium” means any substrate in which insects live or occur. This term encompasses any substrate, including living organisms such as plants and animals, as well as structures such as buildings and soil. Further, in laboratory experiments, the term “habitat medium” includes artificial media other than substrates in which a target insect lives or is settled in a natural environment. Further, in the present invention, the term “vibration” means something that is propagated through a substrate other than air as a medium. Therefore, although “vibration” in the present invention does not include the sound per se that is a stimulus on hearing, for which air is the medium, this term does include the vibrations in the medium that produce the sound. In the present invention, the expression “control an insect pest” includes, in addition to reducing the habitat density of an insect pest in a habitat medium, reducing the damage to the habitat medium by the insect pest (feeding damage, transmission of other harmful organisms etc.).

  • Super-magnetostrictive elements are elements that expand and contract due to changes in magnetic field, and are formed from a lanthanoid element and an iron-group element. Super-magnetostrictive elements are practically used as an actuator or a sensor in mechanical, architecture, medical, and environmental fields. Magnetostriction is a phenomenon in which magnetic permeability (how easily magnetism passes through an object) changes when the shape of an object is caused to expand and contract due to magnetism. Therefore, a super-magnetostrictive element is an element in which this magnetostriction is strong, with amount of the change reaching 1,500 to 2,000 ppm, and also a high rate of the change in the order of nanoseconds to milliseconds.

Vibrations (100 Hz, 2 m/s 2 or more, sine wave, duration 100 ms, interval 900 ms) were applied to one of the habitat media (vibration-applied block), and not applied to the other habitat medium (non-applied block).
  • the Japanese pine sawyer can be controlled by applying vibrations to the habitat medium where this insect pest species lives to suppress behaviors such as oviposition, feeding, and mating, and/or induce behaviors such as escape, freezing, and warning.
  • the oak platypodid beetle which is a serious insect pest of broadleaf trees, such as oaks, also generates sound by rubbing the tip of its abdomen with its elytron
  • Non-Patent Document 4 the fact that the oak platypodid beetle communicates using this sound is already known (Non-Patent Document 4).
  • the frequency of this sound covers a broad band (Table 5), and the amplitude (sound pressure) is also large, it is considered that the oak platypodid beetle also communicates using vibrations on the habitat medium produced by sound.
  • Non-Patent Document 5 Images of these vibration behaviors captured with a high-speed camera were analyzed.
  • the spontaneous vibrations emitted by the Japanese black pine seedlings (4 years old) that were weakened due to pine wood nematode were measured by an accelerometer and an acoustic emission method.
  • the low-frequency component of less than 5 kHz (amplitude 0.002 m/s 2 or more) and the high-frequency component, which is in the ultrasonic range, acoustic emission (frequency of 20 kHz or more) (Table 7) increase and decrease in conjunction with changes in the moisture content over time, which is a cause of pine weakening.
  • Vibrations (100 Hz, 5 m/s 2 , sine wave, stimulus time 1 s or more) were applied by a vibration exciter using a signal generator, an amplifier, and a super-magnetostrictive element ( Figure. 3 ) via a steel wire to the femur of a leg having a chordotonal organ ( Figure. 2 )
  • Figure. 3 A large number of individuals at resting posture was significantly observed that exhibited an escape behavior or a sound-generating behavior, and of individuals that moved their legs and antennae Individuals showing no response to the vibrations were not observed (Table 10)
  • a control group when touched with a steel wire without applying vibrations, most of the individuals showed no response, and they continued moving their legs or antennae, or continued resting. Hardly any individuals were observed that exhibited an escape behavior or a sound-generating behavior (Table 10). Based on the above results, this species is considered to exhibit an escape or a warning response by sensing vibrations with the femur having a chordotonal organ
  • vibrations 100 Hz, 2 m/s 2 , sine wave, duration 100 ms, interval 900 ms
  • the method of the present invention can repel the Japanese pine sawyer, so that the number of feeding individuals of the Japanese pine sawyer can be reduced more than the chemical-based method.
  • the method according to the present invention enables the spread of the Japanese pine sawyers infesting pines due to the feeding of the Japanese pine sawyer to be suppressed very efficiently and safely, thereby allowing damage to pines by the Japanese pine sawyer to be prevented Consequently, the present method is considered to be very effective method for pine conservation, which can replace chemical-based control methods.
  • vibrations were applied to a habitat medium (small balsa sheet), and the behavioral response (escape, warning) of the Formosan subterranean termites was observed.
  • the minimum amplitude threshold for inducing a response was measured (two replicates) by applying vibrations (sine wave, duration 100 ms, interval 900 ms) with three different frequencies (50 Hz, 1 kHz, 5 kHz) on 50 individuals (mixture of workers and soldiers), while varying the amplitude between 0.05 and 24 m/s 2 .
  • the present invention enables insect behavior to be controlled. More specifically, the present invention can be applied not only to control insect pests, but also to attract natural enemy insects, for example. In addition, the present invention can also be applied in the conservation and management of rare species. It is considered that the present invention can make a great contribution to the development of environmentally-friendly control technologies as a substitute for chemical agents. Therefore, the present invention will greatly contribute to the development of the insect pest control industry as well as environmental conservation and related industries.
